From: Sylvain Gault <sylvain.gault at gmail.com>
For the compression / decompression to succeed, the sections layout must
be the same between the virtual memory and load memory. The section
alignment was kept in sync by introducing aligment that should be
greater or equal to the actual section alignment.
This patch compute the load memory addresses of the sections so that
the layout is the same as the virtual memory addresses.
